BAND-CUTTING VF'EGEDERU F R TH RASHlNG-MACHINES.

SPECIFICATION forming part of Letters Fatent No. 325,736, dated September 8, 1885.

Application filed Jilly 22, 1884. (No model.)

To all whont it may concern: g

Be it known that 1, JAMES B. DAVIS, a citizen of the United States, residing at Eureka Springs, in the county of Carroll and State of Arkansas, have invented a new and useful Band-Cutting Feeder for Th'rashing-Machines, of which the followingis a specification, reference being had to the accompanying drawlugs. l

This invention relates to band cutters and feeders for thrashing-machines, and is an improvement on Letters Patent N 0. 199,172, granted to Henry K. Andrews, January 15, 1878. In said patent only one cutter and feeder is employed; consequently the machine'is intended to feed only one sheaf at a time. Practicehas demonstrated that such a construction will not cut the bands and feed the grain upon the carrier in asatisfactory manner; and for the purpose of remedying the various defects in the construction shown in said patent I'have devised certain improvements, which will make the operation of the machineasuc-' cess in every particular.

y The said invention consists in certain details of constructiona'nd combination of parts, hereinafter set forth,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective'view of my improved band-eutter and feeder. Fig. 2 is aside View, showing the side opposite to that illustrated in Fig. 1. Fig'. 3 is a longitudinal sectional view. Fig. 4 is atransverse section on the line at m, Fig. 3. Fig. 5 is a transverse section on the line y Fig. 2. Fig. 6 is a detail view of one of the cutters, showing the manner of securing the knives in place.

The same letters are used to indicate 'corresponding parts in the several figures.

curved plates D D, to be secured to the sides of the thraslier to hold the machine steady and in place.

Shafts B Barejournaled in the under side of the base-board,at the ends thereof, and provided with flanged pulleys O 0, around whichpass the belts dot the carrier E, eross-.

bars c connecting the belts, and the flanges on the rollers or pulleys serving to prevent the lateral displacement of the carrier when the machine is in operation. I do not limit myself to this special construction of carrier. as

various modifications may be resorted to without departing from the spirit or scope of my invention. V

F F designate spring-metal standards attachedat their lower ends to the baseboard a of the frame at the feed end of the machine and projecting upwardly,and secured at their upper ends to the sides of guideboards G G, the latter being inclined, as shown, and supported solelyby the spring-standards on each side of the frame above the carrier, so that shoulda sheaf be fed to the machine which is larger than the ordinary size the guide-boards will yieldoutward, by reason of the flexibility of the springs, and permitthe'passage of the same, and thus all danger. of clogging will be obviated. A vertical guide-board, H, is arranged between the inclined guide boards G,

above the carrier, and is supported inplace by bracess I I, attached to the. outer end, and

curved spring-supports J J, secured to the inner end, the ends of the braces I being ad- 'justably attached'to the sides of the baseboard a, while the ends of the spring-supports J .are connected to the'side boards, a. The said spring-supports not only serve as a means of attachment for the dividing or vertical guide-board, but by reason of their peculiar form they prevent the sheaves from scattering or working upward as the bands are cut- K designates a revolving shaft journaled in A bearings in the side boards, a, and provided at one end with a pulley, d, connected by a belt, L. with a pulley, f, on the outer end of shaft B, and having at the other end a pulley or band wheel, M, to which-motion may be imparted bya suitable belt from thethrasher, or by other suitable driving means. Two cutter heads or burrs, N N, aresecured 'on the shaft K at suitable distances apart, so'as to come indirect lineiwith the feeding-chutes O O,fformed by the guide-boards G G H, said heads or burrs comprising half-scctionsz' i,

formed on their inner adjacent faces with dove-- tail slots or grooves m m, to receive the knives held securely in place and cannot fly out when the machine is in motion. As seen, the outer ends of the knives are curved outwardto a point, the sharpened edges of the knives facing the chutes and the shaft K turning the same in a forward direction, so as to cut the bands of the sheaves as the latter are fed alongby the carrier.

O O designate parallel bars extending transversely across and connecting the upper edges of the side boards, a, the inner sides of the bars 0 0 being beveled or cut away to form ways 1' and receive the slotted extended ends P of a spreader-frame, Q, the latter being arranged between the bars 0 O, and adapted to be reeiprocated from one side board, a, to the other. The said spreader consists of the extended ends P, connected by longitudinal bars 8, to which is secured a perforated plate, t, a pin, 11, on the end of a pitman, R, passing through the perforation of said plate and secured therein. The other end of said pitman connects with a crank, v, on the upper end of a shaft, S, working through a bracket-plate, T, attached to one of the side boards, a, the lower end of the shaft being journaled in an extension, U, ofthe side board. A gear-wheel, V, is mounted on the lower end of the shaft, and engages with another gear-wheel,W, which works through a slot, w, of the extension U, the latter wheel, W, being mounted on one end of a shaft, X, journaled to the under side of the base-board. Said shaft X is provided at its other end with a band-wheel, Y, connected by a belt, Z, with a pulley or band wheel, A, on the end of shaft B, so that the rotation of this band-wheel, caused by the movement of the carrier, effects, by the intermediate mechanism described, the reciprocating movement of the spreader-frame. rods, 9 g, are secured to the frame, and extend or curve downwardly and then forward, the rods g being arranged in rear of the large rods g.,and of a much less curvature, the said spreading-rods being adapted to scatter or spread the straw over the entire surface of the carrier preparatory to depositing the same into the thrasher.

It will be seen that the base-board a is cut away at h to receive the flanged pulleys O, the carrier working at the ends of the machine over the portion of the baseboard intermediate of the pulleys, and guided by the flanges of the pulleys in its movements, so that said carrier will always work true and correct.

' The parallel bars 0 0 should be either constructed of steel or have their inner sides forming the ways 1" faced with the same material.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the annexed draw- A series of spreading ings. Motion is imparted to the machine by the belt from the thrasher, causing the shaft K to revolve, which revolution is transmitted to the carrier by the pulleys d f, connected by the belt L, and by the movement of the carrier the shaft B, together with the intermediate mechanism hereinb'efore described, causes the spreader to move laterally along the ways 7' of the bars 0' 0. Thus the movement of the carrier effects the movement of the spreader, so that when the carrier stops the spreader will cease moving likewise. The sheaves are introduced into the feeding-chutes O 0 between the adjustable guide-boards, and by the movement of the carrier they are drawn forward under the cutters, the knives of which revolve forward to cut the bands, allowing the sheaves to separate, the feeding of the separated grain being kept up so as to pass under the spreading-rods of the, spreader to scatter or spread thestraw or grain over the entire surface of the, carrier, and then feed the contents of the carrier to thethrasher in the manner well known in the art.

It will be seen that by employing the double arrangement of feeding-chutes and cutters I am enabled to perform the work with more satisfactory results than heretofore. The flexibility of the guide-boards allows the passage of sheaves of varying sizes, and the curved spring -supports prevent the sheaves from working upward while being acted upon by the knives. The operation of the spreader is also more effective in its results, causing the thorough scattering of the grain over the carrier preparatory to depositing the same in the t ras e The improved band-cutter and feeder is simple in construction, can be manufactured at a slight cost compared to others of its kind, and works efficiently and cannot work out of order.

Having described my invention, I claim- I. In a band 'cutter and feeder, the combination, with the carrier, of the double arrangement of feeding-chutes, comprising the inclined guide-boards and springs, whereby they are supported above the carrier at'each side of the frame, the vertical guide-board arranged between the inclined guideboards, and spring-rods supporting said vertical guideboard, as set forth.
